A Mo-Cu-Ag-Au-Pb-Zn-As-Sb-Bi mine located in the W½ sec. 11, T8S, R18E (Oak Grove Canyon 7.5 minute topo map), 3½ miles N of Sombrero Butte, just N of Copper Creek in the Copper Creek Canyon, and 11 miles E of the town of Mammoth. Discovered in 1883 by Aldwinkle and grubstaked by Childs. Owned by the Arizona Molybdenum Corp. (1933-1938). Also known as / designated: The Calumet and Arizona Mining Co. property; Arizona Molybdenum Corp. property; Table Mountain Copper Co. property; Patented claims MS 3263; Minnesota-Arizona Copper Co. property; and the Copper Creek project (in part).

The orebodies are breccia pipes. There are two ore bodies. The south ore body is 220 X 100 feet, the Alamo ore body is 270 x 150 feet in size. The breccia pipes probably join at 700 feet and pinch out at 800 feet. The ore minerals are confined to the cementing material where they occur as disseminations and lining of fractures. The ore body is funnel-shaped and tapering downward. Ore control was a breccia pipe at fault and fracture intersections. Alteration was sericitic, chloritic, tourmaline, silicification and oxidation to iron oxides in the outcrop. Associated rock unit is the Copper Creek granodiorite, a porphyritic biotite granodiorite. Bornite, tennantite were important at depth. Molybdenite was confined to open spaces. The bulk of the chalcopyrite is interstitial to breccia fragments. Molybdenite, the latest sulfide, is later than many gangue minerals. The breccia pipe may have a zoned sulfide mineralogy. The Au, Ag, As, Sb, and Bi were derived from treatment of the copper concentrates.

Area structures include Tertiary block faulting trending NNW and the breccia pipe in strong E-W vertical faults and fractures with N60°E and N70°W strikes.

Two ore bodies were developed, the South and Alamo bodies. Workings included 2 adits, 5 levels below the haulage level, a 2-compartment winze, and 2 large glory holes on surface. Workings were to the 850 level (1938). Most workings are now inaccessible. Production was 6,454,321 pounds of MoS (1933-July, 1938), 5,519,140 pounds of Cu, 19,167 oz. Ag, and 4730 oz. Au.

Assay data: Mo grade 0.4-0.75%, Cu grade 3-4%. Molybdenite nearly constant at 1-2%. Cu content increased from 1% at surface to 6-8% at the 800 feet, then decreased to 2% at the bottom of the mine.

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
